To all 'whom it may concern:

Be it known that I, NORTON WAGNER, a V- citizen of the 'United States,- residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certainnew and useful lllrnprovernentsinInk-Folin#` 1s a specifi-l tains, of which the following cation.

My invention comprises improvements in' ink fountains'for printing presses, the details and advantages of which-will beelearV from the following specification, taken in connection with'the accompanying drawing, in which,

Figure l is a top plan view of the' ink fountain, andV the supporting. arm for connecting it to the press; Fig. 2 1s a side elevation of the saine g' Fig. 3 is acentral vertical section taken longitudinally. through the'A fountain; Fig. et is a side view, partly in` section, of a portionof the lever for operating' the feed roller, showing theA pawl and ratchet wheel; Fig. 5 is a side View of the -screw for retaining and locking .theadjusting screw; and Fig.- 46 is )a Vverti :al sectionr on the line 6 6 of F -ig 1, and FiO. 7A is a) .perspective view of. a wedge-shapedn for adjusting the level of the ink 'fountain Referringto the drawhig9 A indicatesthe ink fountainj'B the supporting arm for attaching it to a pri-ntingjpress, .Othe rotatable ink plate ordiskof the press', and-D' the usual bracket on the pressfor-support-` ing the disk.

The ,ink fountain vcomprises an outer rec:

tangular metal box or casing a, ,open at .the f top, and having a feed roller b ittin-gbetween the sides 1 and 2 at one endof the casing and closing said end.`v This roller.

is'rnounted upon ,a shaft c which extends through and isjournaled in the sides of the easing, at their ends. Within' the' casing al is arranged alsliding ink troughgd having .sides Bland 4 parallel with the sides l and 2 respectively, and kfitting closely against ythe sides of the rollerv at their'forward ends,

as shown in Fig.v 1.' yThe-bottonu of the r trough slopes'from the rear, orleft vhand tom of the casing leaving an opening be-.v tween the roller and the forward end of theend in the drawingytoward the roller, and the 'forward end 5a ofthe bottom of the ltrough is concave, as shown, tofit the con- Vex surface of the roller. The sides land 2' of the outer -casing extendbeyondthe bot= botton 6. The forward end of the bottom washer Y of the trough d 'rests upontheforward end of the botton1"6,as shown `in Fig. 3'. 4The trough disadjustabletoward and from the rollerby 'means of an adjusting. screwze -whichi's threadedv into a Ylug ZV on the under side'ofthel bottom Vofthe trough; This'ad-j' Vjusting screw extends .through a vertical slot .8 inthe rear end of thel outer casing and has ashoulder 9 which abuts against the casing. l, c f y The adjusting screw e' has 4an annular groove f1Q,--and ascrew E, Figs. 1, 3a'nd 5,- lextends across the rear end vofg the casingabove the adjusting screw and has a reduced en'd orpintle llwhichfitswithin the an-y nular groove andnormally preventsv the adjusting screwl from being moved upwardly. out of the slot'- 8'; The retaining screw E lalso has a? tapered portion 12 which,A when the screw'lis turned inwardly to its full extent, binds againstthe adjusting "screw e and f rlocks the latter'against turning. By loosening thescrew Ethe adjusting'screw c may be .turned to adjust the trough toward or from the rollerl andthus adjust the width of the opening between the curved Lendfa. of the' I bottom of the trough andthe face of the roller so'as to permit'more' or less ink to be 1 fed out o f the trough onthey face ofl the roller when the latter -is rotated l Theink fountain` is supported'upon the arInB lby'nieans of a yokevF bolted to'said bei-ng such that ,by adjusting the s'crew G the roller b may be raised orlowered relative to the ink disk C, and the forward end of the ink fountain may swing upwardly about its pivotal support 13,.

" The shaft c has a key-way 14 extending throughout its lengt-h and the roller has a spline or. key 15 integral therewith which ts'withinthe key-way so that the shaft and roller turn together.4 A ratchet wheel H is :also fitted upon the shaft and provided with 'an integral'key or. spline 16 which fits within the key-way- 14. This ratchet wheel is ar4 ranged within a vertical slot 17 in a lever L and'a'pawl l8-'pivoted between the walls of said` slotl is adapted 'to engage the teeth of the ratchet wheel. One arm` 19 of the lever-I is made heavy enough .to rock the arm in one direction by gravity, and theI opposite arm 20 of the lever has connected thereto a chain 21 by which the lever may be attached to a reciprocatingpart of the printing pressso that the arm will rock` in the direction to feed ink by movement of the part of the press to which the chain is attached, and will move in the opposite direction by reasonof the weighted arm 19. i

It will be` noted that by providing the roller and ratchet wheel with splines or keys which t within the groove or key-way in theshaft the lever, ratchet wheel, roller, and shaft may all be readily taken apart by removing the Cotter-pin 20 from the end of the shaft, and may be as readily assembled. It is` desirable to have the parts readily removable forv the purpose of cleaning the fountain, which is necessary from time to time in.

practice and particularly when an ink of a different color is to be placed in the fountain.

` It will also be noted that by providing the key-way in the shaft and the integral keys within the ratchet wheel and roller there is nothing upon the shaft to interfere with the yinsertion of the shaft through the circular openings or bearings in the side walls of the outer casing and .in the walls of the slot in the lever. The trough d also may be readily removed by unscrewing the retaining and locking screw Eso that the adjusting screw emay be moved vertically upward through the slot 8, and the trough and adjusting vscrew may be lifted out of the outer casing for the purpose of cleaning the trough and casing. By having the parts made so that they can be'readily removed or taken apart much time is saved in cleaning the fountain.

.l vA stop 22 is arranged upon the side 2 of the casing, and stops 23 and 24 upon the lever I coperate with the stop 22 to limit the movement of the lever. The normal positionof the lever is shown in full lines in Fig. 2, and the dotted lines indicate the'position of the lever whenthe arm 20 is pulled downward to its full extent by thechain 21. Each time an impression is taken on the press, the lever is moved from the position shown in full lines to that shown in dotted of the fountain is effected by setting the.

lines, moving the feed roller a denite extent. By throwing the pawl 18 out of engagement with the ratchet wheel H the feed of the roller may be stopped without stopping the press or disengaging the chain from lthe ress.

The arm B is provided with a suitable number of bolt holes 25, so that the fountain 'can be set approximately in the proper posh' tion relatively to the ink disk and ink or form roller, by means of the bolt 26 passing through one of said bolt holes and into the post or bracket D, and the finer adjustment Screw 27, connected with the yoke F, at the proper position within the slot 28 in the end lcasing having a vertical slot feed roller arranged at the opposite endof of the arm B. A Wedge-shaped washer K (Figs. 2 and 7 is placed between the yoke F and the arm B, upon the screw 27 and by turning this washerlto the correct position' the axis of the ink roller may be tilted so as to bring it parallel with the axis of the ink or form roller.

' When in proper position uponthe press, the form rollerwill engage' the feed roller and receive its supply of ink without disturbing the position of the fountain. In

some presses the ink or form rollers travel higher on' the ink disk when the impression is of than when on, and in such case the form roller will passiunder the feedA roller, and the fountain will be moved upward off of the supporting `screw G. In orderl to prevent injury to the composition form roller, when this occurs, the under side of the outer casing of the ink-fountain is made concave, as indicated at 29, so that the roller will not be torn vby the casing, and I also provide a shoe or guard J upon one side ofy the casing whioh'will be engaged by the pulley or trunnion at the end of the form roller, so that the ink fountain will be raised by the trunnion or pulley, engaging the shoe,

instead of by the com fosition roller. This shoe, as shown in Fig. 2, is detachably connected to the side of the outer casing of the fountain by screws 30, passing through a longitudinal slot 31 in the shoe, permitting longitudinal adjustment of the shoe, an

the` arm32 extends to theforward end of the outer casing, below the bottom of the casinfr,

and 'intoposition to be engaged by the puI ley or trunnion of the What I claim is,-

1. An ink fountain form roller.

comprising an 4outer at one end, a

the casing between its sides, an ink trough within the casing, au adjusting screw extending through said slot and enga g the trough, and a locking screw threaexd into the casing above the adjusting screw and transversely thereto, said locking screw being adapted to retain the adjusting screw within the slot and having a tapering part adapted to bind against the adjusting screw. 2. An ink fountain comprising an outer .casing having a vertical 'slot atone end, a l

3. The combination with a suitable supporting arm, of an ink fountain, a device for connecting said fountain pivotally to the arm, and a wedge-shaped washer-between said device and arm, for the purpose set forth.

4. An ink fountain comprising an outer casing pivotally supported at its rear end, a feed roller et the forward end of the casing, and a shoe secured to the casing and extending at one side of the roller below its axis, for the purpose set forth. v

5. An ink fountain comprising an louter casing pivotally supported at its rear end, a feed roller at the forward end of the casing, and a shoe secured to the casing at one side of the roller, said shoe being adjustable longitudinally of the casing.

6. An ink fountain comprising an outer casing pivotally supported at its rear end and a feed roller at the forwardqend of the casing, the under side of said casing being' concave adjacent to the roller, and a shoe.-

secured to the casing and extending at one side ofthe roller.

7. A11' ink fountain comprising an outer casing havin-g g feed rollerarranged at the opposite end of the casing between its sides, within the casing, an adjusting screw eX- tending through said slot and engaging the trough, said adjusting screw having an annul'ar groove, and a threaded locking device extendlng. over the screw and fitting-into said annular groove.

In testimony whereof I affix my signature, in presence of two Witnesses.
